Changes

tsk18 Adds views for teams management
We added 3 views: list, add and edit teams. In the list view we have 2
search types (by name/description and by sport type) that search for the
user managed team applying this filters. In the add view we created a
form that allows to create a new team. In the edit view we have a form
that loads data from a a team and allows to change it. In the
TeamManagedBean we had removed some source code from some functions
because we have security roles but we don't have yet a login
implementation. In this cases we added a comment indicating what should
be implemented.
